术语askarel通常描述广泛使用的一类不可燃合成卤代烃绝缘液体。在本指南中，其仅适用于以工频运行的变压器、电抗器和附属设备中的askarel。Transformer askarels含有PCB（多氯联苯），在过去40年中，美国和其他地方已将其用于许多工业和消费应用。最近，越来越多的证据表明，多氯联苯广泛分布在整个环境中，可能会产生不利的生态和毒理学影响。1972年5月的联邦跨部门工作组报告COM-72-10419《聚氯化联苯与环境》/*建议限制PCB在变压器和电容器中的使用。askarel和askarel的处理和处置方法- 美国国家标准草案《含多氯联苯的电容器和变压器级Askarels的处理和处置指南》C107中给出了浸渍材料。1本指南帮助电力设备操作员评估以工频运行的变压器、电抗器和附属设备中的askarel，并努力将askarel保持在可用状态。它建议采用标准化的测试和评估程序。概述了必要时修复和回收askarel的方法。

The term askarel generally describes a widely used broad class of nonflammable synthetic halogenated hydrocarbon insulating liquids. In this guide, it applies solely to askarel in transformers, reactors, and accessory equipment operated at power frequencies. Transformer askarels contain PCB's (polychlorinated biphenyls), which have been used in the United States and elsewhere over the past 40 years for many industrial and consumer applications. Recently, evidence has accumulated to indicate that PCB's are widely dispersed throughout the environment and that they can have adverse ecological and toxicological effects. The Federal Interdepartmental Task Force report COM-72-10419, 'Poly chlorinated Biphenyls and the Environment/* dated May 1972, has recommended restricting PCB's to use in transformers and capacitors. Methods for handling and disposal of askarels and askarel-impregnated materials are given in Draft American National Standard, Guidelines for Handling and Disposal of Capacitor and Transformer-Grade Askarels Containing Polychlorinated Biphenyls, C107.1 This guide assists the power equipment operator in evaluating askarel as received in transformers, reactors, and accessory equipment operated at power frequencies and in his efforts to maintain askarel in serviceable condition. It recommends standardized tests and evaluation procedures. Methods are outlined for reconditioning and reclaiming askarel whenever necessary.
